More than 40 percent of students in California's public schools speak a language other than English at home. In the 2016-17 school year, 21 percent of all students, or more than 1.3 million, were English Learners (ELs). When former English Learners are included, the population of "ever ELs" expands to 38 percent of all K-12 students in…

Gestures are associated with powerful forms of understanding; however, their causative role in mathematics reasoning is less clear. We inhibit college students' gestures by restraining their hands, and examine the impact on language, recall, intuition, and mathematical justifications of geometric conjectures. We test four mutually exclusive…

We study the usage of a self-guided online tutoring platform called Algebra Nation, which is widely by middle school and high school students who take the End-of-Course Algebra I exam at the end of the school year. This article aims to study how the platform contributes to increasing students' exam scores by examining users' logs over a three year…

This report provides a comprehensive look at computer science (CS) education across Utah elementary, middle/jr. high, and high schools as of 2018. The Utah Expanding Computing Education Pathways (ECEP) team sent out a survey to all public schools in the state of Utah. The survey presented targeted questions depending on whether it was completed…

Recent research in implementation science has focused on identifying factors that predict adoption of evidence-based practices in schools. Less attention has focused on examining the adoption of practices within districts. This study included a sequential cohort of 552 districts in 25 U.S. states adopting an evidence-based framework, school-wide…

Nearly two-thirds of the Hispanic/Latinx college students in the United States attend Hispanic-Serving Institutions (HSI). Yet, very little research has been conducted regarding these colleges and universities. To address this concern, a sequential, exploratory investigation was conducted with funding from the National Science Foundation (award…

In this article we examined predictive validity of Student Risk Screening Scale for Internalizing and Externalizing (SRSS-IE) scores for use with elementary-age students (N = 4,465) from 14 elementary schools. Results indicated elementary school students with high levels of risk according to fall SRSS-IE scores -- especially those with…

A tenet of multitiered systems of support and response to intervention (MTSS/RTI) is that lack of response to instructional intervention is explained by classroom experiences and behaviors given opportunities to learn. We investigated the potential of filling this information gap in MTSS/RTI decision making using ecobehavioral observation to…

Why do people change their strategies for solving problems? In this research, we tested whether negative feedback and the context in which learners encounter a strategy influence their likelihood of adopting that strategy. In particular, we examined whether strategy adoption varied when learners were exposed to a target strategy in isolation, in…

Although peer-mediated interventions can provide effective pathways for enhancing the social outcomes of students with autism spectrum disorders (ASD), their application within secondary schools has been fairly limited. In this exploratory study, we examined the implementation of peer support arrangements and peer networks for 102 adolescents with…

This study examined why some seniors attending Early College High Schools did not plan to continue their education at a 4-year college immediately after graduation despite attending schools designed to provide coordinated academic and social supports with the expectation that all students would continue their education. Most students in our study…

We compared students' performance on a paper-based test (PBT) and three computer-based tests (CBTs). The three computer-based tests used different test navigation and answer selection features, allowing us to examine how these features affect student performance. The study sample consisted of 9,698 fourth through twelfth grade students from across…

A common goal of Intelligent Tutoring Systems (ITS) is to provide learning environments that adapt to the varying abilities and characteristics of users. To do this, researchers must identify the learning patterns exhibited by those interacting with the system. In the present work, we use clustering analysis to capture learning patterns in over…

Efforts to improve the achievement gap between low-income children and their more affluent peers has led to the development of classroom interventions and curricula to increase executive functioning (EF) and social-emotional skills (SE), thought to be foundational for learning. The Second Step Early Learning (SSEL) curriculum is a commercially…

This study employs data from both kindergarten cohorts of the Early Childhood Longitudinal Study (n ~ 12,450 in 1998; n ~ 11,000 in 2010) to assess whether associations between preschool participation and children's academic and behavioral outcomes--both at school entry (Mean age = 5.6 years in both cohorts) and through third grade--have changed…
